RAILROAD-SIGNAL.

SPECIFICATION forming part of VLetters. Patent No. 408,81557, dated August 13, 1889.

Application filed April l1, 1889.

To all whom, it may concern:

Beit known that I, CHARLES T. HALLOWELL, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Railroad-Signals, which im-' provement is fully set forth in the following specification and accompanying drawings.

My invention consists of a railroad-signal in which the signal-arm may be illuminated the color that it is desired to display, so that at night said color is presented in the arm.

Figure l represents a perspective view ofa railroad-signal embodying my invention. Fig. 2 represents a top or plan view thereof. Fig. 3 represents a vertical section of detached portions.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A designates a pole, post, or standard, to the upper end of which is secured a segment orsegmental piece B, of metal or other suitable material.

C designates a signal-arm, which is pivoted to the pole and carries at one end thereof a lantern I), within which is hung a swinging lamp E, it being noticed that the parts are so disposed that the segment B occupies a position between the arm C andrlante'rn D.

Connected with the segment at intervals are pieces F, of glass or other transparent material, which may be denominated bnlls-eyes, and the side of the lantern adjacent to the segment is open, so that the lamp E is permitted to directits light to said bulls-eyes, the side of the lantern opposite to its opening having a reflector G for evident purposes.

To the end of the signal-arm adjacent to the lantern (see Fig. is secured a guard H, which is of segmental form and circumscribes the segment B, so as to cover the portion of said segment or of the bulls-eyes not in use from snow and ice, said guard, as is evident, moving with the arm and being formed of metal or other suitable material. The guard is partly removed in Fig. l. The si gnal-arm is hollow or tubular, having one or more sides formed of transparent material, (preferably glass,) the end near the pivot or axis being' Serial No. 306,862. (No model.)

adapted to coincide in position with either of the bulls-eyes of the segment.

The operation is as follows: In the present case three bulls-eyes are shown-red, green, and white in color; but it is evident that different colors and numbers may be employed, as desired. The arm may be set to either bulls-eye according to t-he signal to be displayed, and it will be seen that the arm will be illuminated the color of the bulls-eye with which it is in communication, thus producing a signal for night that is effective and reliable and cannot be misunderstood. For day purposes the arln appears comparatively the same as in the ordinary signal and may be operated as such. During the motions of the lantern the lamp, owing to its pivotal or axial support, preserves its upright position.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is v 1. A signal having a movable transparent signal-arm, stationary color-imparting material adapted to coincide with said arm, and a lantern attached to said arm, said lantern having a lamp adapted to illuminate said material and transmit the color thereof to the signal-arm, substantially as described.

2. In a signal, color-imparting material attached to a stationary holder, a swinging transparent signal arm or standard, and a lantern having a lamp which illuminates said material and transmits the color thereof to the arm, said lantern being connected with the signalarm and movable over the color-impartin g material, and the lamp of the lantern being pivotally supported with the lantern, the parts being combined substantially as described.

.3. A signal consisting of a segment having pieces of transparent material of different colors, a pivoted arm provided at one end with alantern having a swinging lamp therein, the said lantern having an opening adapted to coincide with either of said pieces, and a reflector opposite said opening, said parts being combined substantially as described.

4. In a signal, the segment having pieces of transparent material of different colors, a pivoted arm carrying a lantern, the latter having a swinging lmnp therei n and provided wi th an opening coinciding with either of the Said pieces, and :L guard secured to said hintern :md adapted to @over said Segment, said parts being Combined substantially as described.

5. A signal consisting of a seg11\ex1t,the 121tier having' bu11s-eyes therein, and :L pivoted :u'ni having f1-lantern with :L swinging lmnp :nid :in Opening` coinciding with either 0E Said hnlls-eyes, Said mni beingheilewzindhaving 1o a transparent side, the parts named being` combined Substantially as described.
